Research on mineralogy and flotation for coal-series kaolin

The influence of grinding time and pH on the flotation was researched so as to determine the optimal flotation conditions. The results of froth flotation showed that the mass fraction of pyrite in kaolin concentrate was 0.11% at 1.12% pyrite in the flotation feed, and hence 90.72% of total pyrite was separated by froth flotation.

The flotation practice and the previous studies have demonstrated that chalcocite flotation can be depressed by the slime coating of clay minerals (Peng and Zhao, 2011; Zhao and Peng, 2012).

The interaction of clay minerals and saline water in coarse coal flotation

1. Introduction. Clay minerals often associate with valuable minerals in a great range of ore bodies and have a substantial impact on the efficiency of many processes including grinding, pumping and dewatering, etc. when valuable minerals are extracted [1], [2], [3].In mineral flotation, a number of studies have demonstrated that clay slime …

Slime coatings in froth flotation: A review

Slime coating is a significant phenomenon in froth flotation. The adverse effects of slime coating, by which a value mineral is covered by slimes and prevented from direct contact with collectors and/or air bubbles, have been recognized for decades. It happens ubiquitously in the flotation of various minerals, including sulfide minerals ...

In grinding, they usually vary between 65% solids in ball and pebble milling to 85% solids in rod mill grinding of high specific gravity sulphides. The more common ores are ground between 70% and 80% solids. Rougher flotation will most efficiently be conducted between 25% and 50% solids and the usual range is from 35% to 45% solids.
